RAILWAY-RAIL JOINT- SPECIFICATION forming part of Letters Patent No.750,859, dated February 2, 1904.

Application filed October 27, 1903. Serial No. 178,755. (No model.)

To roll whom it puny concern:

Be it known that I, TILLIAM RUFFNER KA- NARR, a citizen of the UnitedStates, residing at Marion Center, in the county of Indiana and State ofPennsylvania, have invented a new and useful Railway-Rail Joint, ofwhich the following is a specification.

This invention relates to the joints between the ends of railway-rails,and has for its object to simplify and improve such devices and producea joint which will not require clamp-bolts or other extraneous fasteningmeans to hold the rail ends together, but which will be held entirely bythe interlapping and interlocking form of the structure and theholding-spikes by which it is secured to the ties.

The invention consists in certain novel features of construction, ashereinafter shown and described, and specified in the claims.

In the drawings illustrative of the invention, in which correspondingparts are denoted by like designating characters, Figure 1 is a sideelevation. Fig. 2 is a longitudinal sectional elevation. Fig. 3 is atransverse section on the line 3 3 of Fig. 2. Fig. A is a perspectiveview of the adjacent rail ends, illustrating their construction morefully. Fig. 5 is a perspective view of the tie-plate detached. Fig. 6 isa detached perspective view of the lock-block.

The adjacent rail ends 10 11 are formed to overlap by cutting away thelower portion of one rail to form the overhanging tongue-like projection12 and the upper portion of the other rail end to form the tongue 13,the tongue 12 carrying the rail-head and fitting in the cut-out space ofthe rail end 11 and overlapping the tongue 13. These tongues and therail ends at the base of the tongues are preferably thickened or widenedlaterally to approximately the width of the rail-heads.

Centrally formed in the adjacent faces of the tongues 12 13 areoppositely-disposed recesses or cavities 1A 15, adapted to register whenthe rail ends are united, as shown in Fig. 2, and in these cavities isdisposed a keyblock 16, fitting the apertures transversely relativelyclose, but preferably made shorter Disposed beneath the adjacent andinterlapping rail ends is a tie-plate 18, preferably of steel ofsufficient thickness and having lateral brace portions 19 2O benttherefrom for engagement with the opposite base-flanges of the rails,the braces being long enough to overlap'the base-flanges of eachrail-section and afford ample support thereto, as shown.

The rail-sections will be provided with spaced apertures 21 22 for theholding-spikes 23 24, and the brace portions 19 20 will likewise beprovided with corresponding spikeapertures 25 26 to engage the oppositesides of the spikes. By this means all the parts will be firmlysupported and held together without the use of transverse bolts orclampplates of any kind, the interlapping form of the joint affordingample support to resist the strains and effectually preventing anydisplacement under the most severe concussions.

The parts are of ample strength to enable them to resist all the strainsto which they will be subjected, and to this end the widening orreinforcing of the rail ends laterally opposite the interlappingportions 12 13 is an important feature of the invention, thebearing-surfaces being thus increased where most required and all dangerof fracture at the joint obviated.

The detachable key-block 16 is also an important feature of theinvention, effectually supporting the rail-sections laterally whilepermitting sufiicient movement longitudinally to provide for theexpansion and contraction of the rails.

The blocks 16 may be of hardened steel to resist heavy strains; but theymay be easily replaced at small expense if broken or worn-out, avoidingthe necessity of replacing the whole rail.

Having thus described the invention, what I claim is 1. In a rail-jointthe combination with the rail-sections having their adjacent endsinterlapping and provided with oppositely-disposed recesses in theadjacent faces of the interlapping portions, and a key-block detachablyengaging said recesses and forming a locking means to prevent transversemovement between the rail-sections.

2. In a rail-joint the combination with the rail-sections having theiradjacent ends interlapping and provided with oppositely disposedrecesses in the adjacent faces of the interlapping portions, and akey-block detachably engaging said recesses and of less widthlongitudinally than the length of the recesses, forming a locking meansto prevent transverse movement while permitting longitudinal movementunder the action of contraction and expansion. 7

In a rail-joint the combination with the rail-sections having theiradjacent ends interlapping and laterally widened or thickened andprovided with oppositely disposed recesses in the adjacent faces of theinterlapping and thickened portions, and a key-block detachably engagingsaid recesses.

4:. In a rail-joint the combination with the rail-sections having theiradjacent ends interlapping and provided with oppositely disposedrecesses in the adjacent faces of the interlapping portions, a key-blockdetachably engaging said recesses and forming a locking means to preventtransverse movement between the rail-sections, and a tie-plate extendingbeneath said interlapping rail ends and provided with integral lateralbraces engaging the opposite base-flanges thereof.

5. In a rail-joint the combination with the rail-sections having theiradjacent ends interlapping and provided with spaced spike-recesses intheir base-flanges and with oppositely-disposed recesses in the adjacentfaces of the interlapping portions, a key-block detachably engaging saidrecesses and preventing transverse movement between the railsections,and a tie-plate extending beneath said interlapping rail ends andprovided with integral lateral braces engaging the oppositebase-flangesof the same, said braces having spaced spike-recessescorresponding to the spike-recesses in said base-flanges of the railends.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

WILLIAM RUFFNER KANARR.
